Chesterton's Fence!

"In the matter of reforming things, as distinct from deforming them, there is one plain and simple principle; a principle which will probably be called a paradox. There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, “I don’t see the use of this; let us clear it away.” To which the more intelligent type of reformer will do well to answer: “If you don’t see the use of it, I certainly won’t let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it."

Yes, but sometimes the road is nothing but gates. By crossing the fence and running across the field, we harm no-one on the road, and we get places.

By crossing the fence you put your car on the train tracks and derailed the on-coming train. Happens over and over again.
